when i was doing cages and backhalfing vehicles i had to look at the car first then talk with the individual and see to what extent they wanted the job done.. how good an actual job the individual had, basicly good background information.. building hardcore costs more than lowbuck, you guys know how that goes.. i would never hang myself out to somone i didnt know at all.. i generally tried to quote stuff at $50 an hour..
if it pertains to machine work, i'm a tool&die guy by trade, so in no way do i want to do machine work for someone else on my free time, so i pretty much try to price it out of range, unless the person that needs the machine work done can build a transmission or something like that, then i try to go to the barter system, and at that point i need to know the person pretty good for the bartering to commence..
if somebody pulls up and needs something welded and it doesnt take 5 minutes to weld, say an alternater bracket or something of the sort, i would probably do something small like that for free, because generally people would possibly comeback to you if they had something a little bigger to weld or fabricate then you can make a lil money...
an example, i had my truck sitting outside oneday clearing out the garage, and a guy with a mowing trailer pulled in and asked if i did fabrication work, he has a successful mowing business, so i say yes sir i do, this guy works at Alcan Aluminum so now i know he has a fulltime job and mows on the side.. we chat a lil, he has broken his trailer in front of the front axle (tandem axle trailer), and needs it welded and reinforced by in the morning, so now its 5:00 in the afternoon, he wants it at 6am, so my price just doubled because i have to work my arse off to get it done by a decent hour for me to get food, shower and sleep for work the next day.. I was afraid to piss the guy off, but what do you do, its after hours, he makes alot of money mowing and at his full time job, i dont want to rape the guy as he might bring more side jobs. but then again he has disrupted my plans of cleaning the garage and whatever else, so i shoot him a price of $500 and he didnt hesitate, he says OK I'll see you in the morning, and no faster than i could say see ya, he was in his truck and gone.. it took me about 3 1/2hrs to fix it, he showed up at 6am on the nose, i was outside jacking the hitch on the trailer for him to latch on.. he jumped out and loved the job i did and handed me $500 cash and asked if i wanted anymore work.. i ended up putting weedeater racks, and ramps on 3 different trailers for him and he paid top dollar everytime.. its all situational..
also, i just built a 4link to have on the shelf.. i probably could have saved money by just buying it outright if you figure it took me 8 hours to draw and program and cut the brackets.. but i now have programs and fixture for the front and rear brackets for a streetrod 4link.. at this point i can cut them in a 1/4 of the time now.. some stuff i will buy , but if i can look at something and say i can make it cheaper, or roughly the same, but make it better, or make it better and make it look even better then i do it myself...
